ional view of 5 are referred Y is connected as the pipe 11 and leads from a suitable source of steam, compressed air,

' therefrom. The' valves 13 are connected by means of a rd14 for simultaneous operation 1f desired. When th doors 2 are closed, they are drawn tight and made-"secure by -supply ing fluid pressure to the cylindersflwhich actuate the pistons to force the wedgefasteners 8 inward, thereby closing and securing the doors by a wedge action. The wedge fasteners, 8, are moved inward by admitting the fluid pressure to the outer ends, of the cylinders 9. Upon operating the valves 13 to admit the fluid pressure totheinner ends :ofthe cylinders, the p stons lO are ;-moved outwardly and withdraw the fasteners 8,

thereby releasing-thedoors which may be quickly opened.

For quick openingof the doors 2, a pair of cylinders 16 is associated witheach, the. cylindersfof each pair being disposedat opposite sidesofthe retort and inclined upwardly and forwardly from their inner lower ends. .0 A pipe 15,connec ts the cylinders 16 with the .3

feed pipe 12 and a three-way valve 17 islocated in the-length ofthe pipe to control the flow of the fluid pressure to thecylinders.

Apiston18. in each 'of the cylinders 16 has rod connectedthereto and extending :through the head of the cylinder and terminating'in a slotted cross head 19 to receive'the pin .20 or like projecting part of the door. When the door is released it may be thrown quicklyinto open position by admitting fluid pressure into the cylinders 1 6 to movethe pistons upwardly and forwardly therein. The doors may close by gravitative 1 action, when the valve 17 is operated to exhaust the spent medium: from the cylinders A pipe 21 connects with one of the doors :2 and constitutes an outlet. A pipe-22 con- ;nects with the opposite door 2 and jsupplies f the medium for'treatment of the material to be processed or dried.- A pipe 23 connects with'the pipe 22 andsupplies oil,;chemical or other medium tobe introduced into the retort. The pipe 22 may lead from a compressor or other source for supplying air under pressure, 'or for receiving steam or other act ve medium employed in the process. A {valve 24 in the length of the pipe 23 admits ofcontrolling the amount of'oil, creosote, or other chemical to be added to the air or steam flowing through theipipe22, .wherebythe mixture may be sprayed intothe retortfor treatment of the material contained therein A certain percentage of the mixture sprayed into the retort-passes off throughjthe outlet21 and is reclaimed in any determinateway, q-Anypresis applied to the pipe 23 to indicate the pressure resulting from the mixture flowing from the pipe 22into'the retort; A gauge 26 may be applied to the outlet 21 to indicate the velocity of the outflow from the retort. Other gauges '27-, 28 and-aamay be applied tothe retort to v indicate temperature, moisture and pressure. The bottom ,ofthe retort may be supplied with rollers'30, as indicated in Figure 6 of the drawings, to receive the material and facili- .ta'te-its introduction into or withdrawal from the retort. If preferred, a track 31 may belocated in the bottom portion of the retort, as -:i ndica-ted in Figure 2 of the drawings, to re- ..ceive trucks 32 upon which the material may be placed, thereby facilitating supplying the materialto the retort or withdrawing it there from;

The numeral 33 designates clamp memb'ers which are connected to pistons 34 inventionisv adapted for general use in the :treatment of timber and other fibrous ma vterial;required to;becured and processed either by: removing moisture therefrom or by impre nating the same with a preservative or insecticide. The doors are quick opening .andclosing and a tight joint is assured and 1 maintained when thedoors are closed, the fasteningmeansoperating by a wedge action which draws the doors into closed position, thereby assuring a tight joint. The'material,' such as timber,,may be clamped and subjected to compressive force during the removal of. moisture therefrom. This is advantageous inpreserving the structure and preventing war-ping, cracking and other objectionable features which detract from the market value of the commodity. Itjis observed that the fastening means for the doors, the dooropening mechanisnnand the clamps are adapted to V be readily actuated by manipulating a valve 1 to admitfluid pressure into the proper cylin- V ders, the actuating mechanism being rendered inactive by exhausting the fluid medium from the operating cylinder. These several opera tions maybe easily, quickly and conveniently effected.bymanipulation of the proper controlling valves aswillbe readily appreciated.

treating timber, it has been found adf A retort constructed injaccordance with the i shaped joints of the doors and the body of the retort to secure and maintain a tight joint. It is further noted that there is an inner joint that between the band? and inner face of the door, and an outer joint, that between the flange .5 and extremity of the body 1, and that these two joints assure a tightclosure to prevent any possible escane of internalnressure. The V-form of the joints and the provision of suitable packing therebetween assure a tight joint which is'essential under certain conditions. l
